Hi good person,
The answer would be no, depending on what you mean by "standard sampler". If you’re referring to the [adsr~] object in Max, then you can place it inside or outside the [poly~] container for multiple instances of your mono-sampler patch. If you want a global ADSR envelope, place one inside your mono-sampler and then use the (target 0) to poly for each of the ADSR values; if you’re referring to the new [polybuffer~] object in Max, I don’t use it, sorry :(
